Management of parameters
By pressing the
button several times, the fourth line will display successively:
Pmax 00010
: Maximum
pressure.
Remote control: at this value, the discharge valve is opened to reduce the pressure, to protect the
scroll compressors units.
Independent operating: At 10 bar, the compressor stops.
HYSTERESIS 0001
: Remote control: Hysteresis between the maxi. pressure and the closed pressure of the discharge
valve (10-1=9 bar)
Independent operating: Hysteresis between the maxi. Pressure and the start pressure of the
compressor.
At P.maxi – hysteresis = 10 – 1 = 9 bar, the compressor starts.
Tmax 00075
:
Maximum temperature (75°C) of the scroll compressor unit.
If the temperature is above 75°C, there is an alarm.
Tmin 00005
:
Minimum temperature (5°C).
If the temperature is below 5°C, there is an alarm.
HM 1 0000
:
Hour meter of the scroll compressor unit 1.
HM 2 0000
:
Hour meter of the scroll compressor unit 2.
HM 3 0000
:
Hour meter of the scroll compressor unit 3.
HM 4 0000
:
Hour meter of the scroll compressor unit 4.
M3121GB0
:
Program N°, V0 is the version (in this example, V0 indicates version 0).

Management of alarms
** ALARM** appears flashing on the third line and the actives alarms appear :
DISJUNCTION 1 (2, 3 or 4)
: Rise of current. If current becomes very high, "DISJUNCTION 1" (2,3 or 4) displays and
the scroll compressor unit 1 (2,3 or 4) stops.
T.MAX 1 (2,3 or 4)
:
Rise of maximum temperature. If temperature of the scroll compressor unit 1 (2,3 or 4)
becomes more than 70°C, "T.MAX 1" (2,3 or 4) displays and the scroll compressor unit 1
(2,3 or 4) stops.
T.MIN 1 (2,3 or 4)
:
Rise of minimum temperature. If temperature becomes less than 5°C, "T.MIN 1" (2,3 or 4)
displays and the scroll compressor unit 1 (2,3 or 4) mustn't start.
